Here's Why Lots Of People Think The World Is About To End

This belief stems from the interpretation of some writings of the ancient Mayans.

Some people believe the Mayan writings predict that we're going to get sucked into a black hole or smash into another planet or something.

Many experts think these writings have been misinterpreted. Many experts think the date everyone is focused on, December 21, 2012, marks a beginning rather than an end. Many experts think the astronomical phenomenon the Mayans might have been predicting actually happened in 1998.

So this sounds a lot like the usual "end of world" dates that come and go without much notice.

Nevertheless, lots of people are freaking out.

In Russia, people are hoarding salt and food. It's not clear why: If the world ends, it doesn't much matter whether you have stored stuff to eat. But some shelves have been stripped bare.

And there's plenty of chatter about the date in the U.S., too. At least one person has apparently committed suicide to frontrun the inevitable. Other people have asked NASA, the astronomical experts, whether they should kill themselves, their children, and/or their pets.

But what is the significance of this date, anyway? Why do some people say the world is going to end on Friday?

The 2012 phenomenon comprises a range of eschatological beliefs according to which cataclysmic or transformative events will occur on 21 December 2012.[1][2][3][4][5][6] This date is regarded as the end-date of a 5125-year-long cycle in the Mesoamerican Long Count calendar.[7] Various astronomical alignments and numerological formulae have been proposed as pertaining to this date, though none have been accepted by mainstream scholarship.

Scholars from various disciplines have dismissed the idea of such cataclysmic events occurring in 2012. Professional Mayanist scholars state that predictions of impending doom are not found in any of the extant classic Maya accounts, and that the idea that the Long Count calendar "ends" in 2012 misrepresents Maya history and culture,[3][10][11] while astronomers have rejected the various proposed doomsday scenarios as pseudoscience,[12][13] stating that they conflict with simple astronomical observations.[14]

Of course, on the off-chance that the world ends, you're going to want to know how it is going to end. There are a whole bunch of theories about that. They boil down to:

We will get sucked into a black hole (or, at least, we'll get close enough to one that its gravitational pull will screw everything up)

The sun will pass through a "galactic plane" that will cause everything to go haywire

Solar flares will fry us

We will smash into a planet called Nibiru

Here are the details, again from Wikipedia:

Other alignments

Some people have interpreted the galactic alignment apocalyptically, claiming that when it occurs, it will somehow create a combined gravitational effect between the Sun and the supermassive black hole at the center of our galaxy (known as Sagittarius A*), thus creating havoc on Earth.[98] Apart from the fact noted above that the "galactic alignment" already happened in 1998, the Sun's apparent path through the zodiac as seen from Earth does not take it near the true galactic center, but rather several degrees above it.[72] Even if this were not the case, Sagittarius A* is 30,000 light years from Earth and would have to be more than 6 million times closer to cause any gravitational disruption to Earth's Solar System.[99][100] This reading of the alignment was included on the History Channel documentary, Decoding the Past. However, John Major Jenkins has complained that a science fiction writer co-authored the documentary, and he went on to characterize it as "45 minutes of unabashed doomsday hype and the worst kind of inane sensationalism".[101]

Some believers in a 2012 doomsday have used the term "galactic alignment" to describe a very different phenomenon proposed by some scientists to explain a pattern in mass extinctions supposedly observed in the fossil record.[102] According to this hypothesis, mass extinctions are not random, but recur every 26 million years. To account for this, it suggests that vertical oscillations made by the Sun on its 250-million-year orbit of the galactic center cause it to regularly pass through the galactic plane. When the Sun's orbit takes it outside the galactic plane which bisects the galactic disc, the influence of the galactic tide is weaker. However, when re-entering the galactic disc—as it does every 20-25 million years—it comes under the influence of the far stronger "disc tides", which, according to mathematical models, increase the flux of Oort cloud comets into the inner Solar System by a factor of 4, thus leading to a massive increase in the likelihood of a devastating comet impact.[103] However, this "alignment" takes place over tens of millions of years, and could never be timed to an exact date.[104] Evidence shows that the Sun passed through the plane bisecting the galactic disc only three million years ago and is now moving farther above it.[105]

A third suggested alignment is some sort of planetary conjunction occurring on 21 December 2012; however, there will be no conjunction on that date.[106] Multi-planet alignments did occur in both 2000 and 2010, each with no ill result for the Earth.[107]Jupiter is the largest planet in the Solar System; larger than all other planets combined. When Jupiter is near opposition, the difference in gravitational force that the Earth experiences is less than 1% of the force that the Earth feels daily from the Moon.[108]

Most scientific estimates, however, say that geomagnetic reversals take between 1,000 and 10,000 years to complete,[111] and do not start on any particular date.[112] Furthermore, the U.S. National Oceanic and Atmospheric Administration now predicts that the solar maximum will peak in May 2013, not 2012, and that it will be fairly weak, with a below-average number of sunspots.[113] In any case, there is no scientific evidence linking a solar maximum to a geomagnetic reversal, which is driven by forces entirely within the Earth.[114] Instead, a solar maximum would be mostly notable for its effects on satellite and cellular phone communications.[115] David Morrison attributes the rise of the solar storm idea to physicist and science popularizer Michio Kaku, who claimed in an interview with Fox News that a solar peak in 2012 could be disastrous for orbiting satellites.[97]

Planet X/Nibiru

Some believers in doomsday in 2012 claim that a planet called Planet X, or Nibiru, will collide with or pass by Earth in that year. This idea, which has appeared in various forms since 1995, initially predicted Doomsday in May 2003, but proponents later abandoned that date after it passed without incident.[116] The idea originated from claims of channeling of alien beings and has been widely ridiculed.[116][117] Astronomers have calculated that such an object so close to Earth would be visible to anyone looking up at the night sky.[116]

For what it's worth, we don't find any of those concerns particularly compelling. But we've been wrong before...

If you're really worried, you can take advantage of America's stocked shelves to hoard some food like the Russians. That way, if we do get sucked into a black hole, at least you won't be hungry.
